EDVJARDS, OF GRAND RAPIDS, MICHI- GAN, ASSIGNORS TO GRAND RAPIDS LOOSE LEAF BINDER COMPANY, OF GRAND r RAPIDS, MICHIGAN, A CORPORATION OF IICHIGAN LOOSE LEAF BINDER Application led July 13,

The present invention relates to loose leaf binders and; its object is, generally, to provide an improved device of that character which may be very economically manufactured; and more particularly, to provide in such a device a binding post having impfoved means for relatively adjusting its members longitudinally and for mounting the post; and further, to provide improved locking means for the binding post.

These and any other and more specific objects hereinafter appearing are attained by, and the invention finds preferable embodiment in, the device particularly described in the body of this specilication and illustrated by the accompanying drawing, in Which Figure 1 is a sectional view of a loose leai binder with the leaf body therein, taken on line 1-1 of Figure 2;

Figure 2 is a sectional view thereof taken on line 2 2 of Figure 1;

Figure 3 is a top plan vienT of means for locking the binding post of the device;

Figure 4 is a sectional vieu7 thereof and of the binding post, taken on line 4 4 of Figure 3; and

Figure 5 is a view in perspective of the binding strips, the binding posts and one of the locking means, shown disassembled.

In the drawing is illustrated a loose leaf binder having covers 1 connected by a flexible back 2 on Whose inner sides respectively are mounted the flap portions 3 of the binding strips 4, 5. These binding strips are desirably made of thin but rigid and tough material oi such character that openings therethrough for the bindincs posts 6 and the spurs 7 of the post-locking means may be readily and easily made at any desired points corresponding in position with the perforations 3 of the particular leaf body 9 which the binder is to contain.

Each of these binding posts designated generally 6 comprises tubular member 10 having an end 11 internally threaded at 12, and a member 13 internally threaded at 14 extending into the open other end 15 of the member 10. A screw 16 is threaded in the end 11 of member 10 and also in the member 13, and has a head 17 clamping the binding 1931. Serial No. 551,928.

5 between it and the end 11 of member It will be seen that this screvs7 16 serves the double purpose of longitudinally adjusting the members 10, 13 to the thickness of the leaf body, and of securing the binding post to the binding strip 5.

Means for locking the free end 18 of the binding post on the binding strip 4 comprises a flat slidable bolt 19 and a bearing member 2O therefor made of sheet metal bent to form a base portion 21 mountedon the outer side of the binding strip 4, and a top portion 22 having in its inner side a recess 23, said base and top portions being connected by the bight portions 24.

The binding strip 4 and the base portion 21 have openings 25, 26 respectively therethrough registering with the recess 23 as seen .v.

in Figure 4. The bolt 19 has a slot therethrough comprising an enlarged portion 27 adapted in one slid position ofthe bolt to receive the free end 18 oi the binding post inserted into said openings 25, 26 and into the recess 23 of the top portion 22, said slot comprising also a narron portion 29 Whose edges in another slid position of the bolt engage in the lateral recess 30 of the reeend of the post to lock the post to the binding strip 4.

The bolt has a second slot 31, parallel with its aforesaid slot, and the top portion 22 has a tongue 32 struck downwardly thereinto, thus providing an additional bearing for the sliding movement of the bolt. It Will be seen that by reason of these slide bearings and by the free. end of the post engaging in the openings 25, 26 under the bolt and in the recess 23 above it, the post is securely held upright in slid positions of the bolt and during its sliding movement.

LThe spurs 7 of the locking device are inserted into the slits 33 of binding strip 4 which slits may be readily made at desired points as the openings 25 are made, or these pointed spurs may be thrust through said binding strip in the absence of pre-formed slits, and being bent over on the under side of said strip, securely mount the locking means thereon.

The invention being intended to be pointed out in the claims, is not to be limited to or by details of construction of the particular embodiment thereof illustrated by the drawing or hereinbefore described.

IVe claim: v

l. In a loose leaf binder: a pair of binding strips adapted to clamp the leaf body between them; .a Ebinding Lpost :comprising :a tubular member 'having .an internally .threaded end, and an internally threaded mem-ber releasably secured to one of said strips and extending intothe open other end of said first-mentioned member a screw threaded in the internally threaded end of said first-mentioned member and also in the second-mentioned member, said screw extending through the other binding strip and having ahead clamping the same between said headand the internally threaded end :of said Yfirst-mentioned member.

2. In a loose leaf binder z-a 'pair of binding str-ips adapted to clamp the -leaf body between them and to -be readily perforated at desired vpoints to receive the hereinafter-mentioned post a bindirngpost comprising longitudinally adjustably connected members extending through perforations in the binding strips respectively, one of said members being mounted on one of said strips; a :lock-ing device adapted to releasably engage A.the other one of said members andhaving spurs adapted to ybe jthrust through the other vbinding strip for securing said device thereto.

3. In a loose leaf 'binder 4a pair of binding strips adapted toelamp the leaf Abody between them, one of said strips having an opening therethrough; a binding post secured :at one end to the other strip and having 'a lateral vre'- cess adjacent its free end :,loeking means 'compris'inga slidable bolt and a bearing member therefor mad-e by. bending a metal sheet Ato form a base portion mounted on the outer side of the .first-mentioned strip and having an opening therethrough, a top portion having in fits inner side arecess registering with said openings, the bolt having a slot therethrough comprising an yenlarged portion adapted to receive in one Vslid position of the bolt the free end of the post inserted into said yopenings and into said top port-ions recess and a narrow portion engaging in the posts recess in another slid position of the bolt to lock the post to the first-mentioned binding strip, the bolt having a second slot and said top portion having a tongue struck :downwardly thereinto provid-ing an'add'itional bearing for the sliding movement vof the bolt.

In testimony whereof we have hereunto set our 'hands at Grand Rapids, Michigan, this 3rd day of July, 1931. c
